Device, method, and graphical user interface for switching between camera interfaces

ABSTRACT

A method is performed at an electronic device with a display, a touch-sensitive surface, and a camera. The device displays a first camera interface on the display for a first virtual camera that produces media with first output dimensions. While displaying the first camera interface on the display, the device detects a first gesture that includes movement of a contact in a first direction on the touch-sensitive surface. The first gesture does not interact with a predefined camera-switching affordance. In response to detecting the first gesture, the device switches from displaying the first camera interface to displaying a second camera interface for a second virtual camera that produces media with second output dimensions different from the first output dimensions. The second camera interface is different from the first camera interface.

RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent ApplicationNo. 61/832,958, filed Jun. 9, 2013, which is incorporated by referenceherein in its entirety.

TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitivesurfaces, including but not limited to electronic devices withtouch-sensitive surfaces that include multiple camera interfaces.

BACKGROUND

The use of touch-sensitive surfaces as input devices for computers andother electronic computing devices has increased significantly in recentyears. Exemplary touch-sensitive surfaces include touch pads and touchscreen displays. Such surfaces are widely used to manipulate userinterface objects on a display or to activate various features of thedevices. For example, a user can use a camera application on the deviceto capture still images or videos.

But methods for switching modes in a camera application are cumbersomeand inefficient. For example, current methods for switching modes orinterfaces in a camera application include the user activating a toggleswitch or navigating through a complex sequence of menus and settingsinterfaces. The toggle switch may be inconveniently placed with respectto the positioning of the hands and fingers of the user when the user isholding the device in preparation for capturing images or videos.Further, toggle switches are not very effective for switching betweenmore than two modes. Thus, a more effective and convenient method ofswitching between camera modes is needed.

SUMMARY

Accordingly, there is a need for electronic devices with faster, moreefficient methods and interfaces for switching between camerainterfaces. Such methods and interfaces optionally complement or replaceconventional methods for switching between camera interfaces. Suchmethods and interfaces reduce the cognitive burden on a user and producea more efficient human-machine interface. For battery-operated devices,such methods and interfaces conserve power and increase the time betweenbattery charges.

DESCRIPTION OF EMBODIMENTS

Many electronic devices have cameras with a still camera mode and avideo camera mode. With advancements in hardware and software, thedevice can support even more modes for the camera. With the increase indifferent modes for the camera, switching amongst them can beinefficient. Typically, the user switches amongst the modes usingswitches, buttons or some other affordances that are displayed atlocations on the display that are not the most convenient (e.g.,navigating through a series of menus and settings interfaces).Particularly, if the device is a touchscreen device, poor placement ofthe mode switching affordances hinders quick access to different cameramodes when such quick access is desirable. The embodiments belowdescribe methods for quickly switching between camera interfaces thatcorrespond to different camera modes. The user switches amongst asequence of at least two camera interfaces using swipe gestures acrossthe touch-sensitive surface in opposing directions. This makes switchingbetween camera modes more efficient and easier to use.

Below, FIGS. 1A-1B, 2, and 3 provide a description of exemplary devices.FIGS. 4A-4B and 5A-5N illustrate exemplary user interfaces for switchingbetween camera interfaces. FIGS. 6A-6G are flow diagrams illustrating amethod of switching between camera interfaces. The user interfaces inFIGS. 5A-5N are used to illustrate the processes in FIGS. 6A-6G.

Exemplary Devices

Reference will now be made in detail to embodiments, examples of whichare illustrated in the accompanying drawings. In the following detaileddescription, numerous specific details are set forth in order to providea thorough understanding of the various described embodiments. However,it will be apparent to one of ordinary skill in the art that the variousdescribed embodiments may be practiced without these specific details.In other instances, well-known methods, procedures, components,circuits, and networks have not been described in detail so as not tounnecessarily obscure aspects of the embodiments.

It will also be understood that, although the terms first, second, etc.are, in some instances, used herein to describe various elements, theseelements should not be limited by these terms. These terms are only usedto distinguish one element from another. For example, a first contactcould be termed a second contact, and, similarly, a second contact couldbe termed a first contact, without departing from the scope of thevarious described embodiments. The first contact and the second contactare both contacts, but they are not the same contact.

The terminology used in the description of the various describedembodiments herein is for the purpose of describing particularembodiments only and is not intended to be limiting. As used in thedescription of the various described embodiments and the appendedclaims, the singular forms “a”, “an” and “the” are intended to includethe plural forms as well, unless the context clearly indicatesotherwise. It will also be understood that the term “and/or” as usedherein refers to and encompasses any and all possible combinations ofone or more of the associated listed items. It will be furtherunderstood that the terms “includes,” “including,” “comprises,” and/or“comprising,” when used in this specification, specify the presence ofstated features, integers, steps, operations, elements, and/orcomponents, but do not preclude the presence or addition of one or moreother features, integers, steps, operations, elements, components,and/or groups thereof.

As used herein, the term “if” is, optionally, construed to mean “when”or “upon” or “in response to determining” or “in response to detecting,”depending on the context. Similarly, the phrase “if it is determined” or“if [a stated condition or event] is detected” is, optionally, construedto mean “upon determining” or “in response to determining” or “upondetecting [the stated condition or event]” or “in response to detecting[the stated condition or event],” depending on the context.

As used herein, the term “resolution” of a display refers to the numberof pixels (also called “pixel counts” or “pixel resolution”) along eachaxis or in each dimension of the display. For example, a display mayhave a resolution of 320×480 pixels. Furthermore, as used herein, theterm “resolution” of a multifunction device refers to the resolution ofa display in the multifunction device. The term “resolution” does notimply any limitations on the size of each pixel or the spacing ofpixels. For example, compared to a first display with a 1024×768-pixelresolution, a second display with a 320×480-pixel resolution has a lowerresolution. However, it should be noted that the physical size of adisplay depends not only on the pixel resolution, but also on many otherfactors, including the pixel size and the spacing of pixels. Therefore,the first display may have the same, smaller, or larger physical size,compared to the second display.

Embodiments of electronic devices, user interfaces for such devices, andassociated processes for using such devices are described. In someembodiments, the device is a portable communications device, such as amobile telephone, that also contains other functions, such as PDA and/ormusic player functions. Exemplary embodiments of portable multifunctiondevices include, without limitation, the iPhone@, iPod Touch@, and iPad@devices from Apple Inc. of Cupertino, Calif. Other portable electronicdevices, such as laptops or tablet computers with touch-sensitivesurfaces (e.g., touch screen displays and/or touch pads), are,optionally, used. It should also be understood that, in someembodiments, the device is not a portable communications device, but isa desktop computer with a touch-sensitive surface (e.g., a touch screendisplay and/or a touch pad).

In the discussion that follows, an electronic device that includes adisplay and a touch-sensitive surface is described. It should beunderstood, however, that the electronic device optionally includes oneor more other physical user-interface devices, such as a physicalkeyboard, a mouse and/or a joystick.

The device typically supports a variety of applications, such as one ormore of the following: a drawing application, a presentationapplication, a word processing application, a website creationapplication, a disk authoring application, a spreadsheet application, agaming application, a telephone application, a video conferencingapplication, an e-mail application, an instant messaging application, aworkout support application, a photo management application, a digitalcamera application, a digital video camera application, a web browsingapplication, a digital music player application, and/or a digital videoplayer application.

The various applications that are executed on the device optionally useat least one common physical user-interface device, such as thetouch-sensitive surface. One or more functions of the touch-sensitivesurface as well as corresponding information displayed on the deviceare, optionally, adjusted and/or varied from one application to the nextand/or within a respective application. In this way, a common physicalarchitecture (such as the touch-sensitive surface) of the deviceoptionally supports the variety of applications with user interfacesthat are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices withtouch-sensitive displays. FIG. 1A is a block diagram illustratingportable multifunction device 100 with touch-sensitive displays 112 inaccordance with some embodiments. Touch-sensitive display 112 issometimes called a “touch screen” for convenience, and is sometimesknown as or called a touch-sensitive display system. Device 100 includesmemory 102 (which optionally includes one or more computer readablestorage mediums), memory controller 122, one or more processing units(CPU's) 120, peripherals interface 118, RF circuitry 108, audiocircuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem106, other input or control devices 116, and external port 124. Device100 optionally includes one or more optical sensors 164. Device 100optionally includes one or more intensity sensors 165 for detectingintensity of contacts on device 100 (e.g., a touch-sensitive surfacesuch as touch-sensitive display system 112 of device 100). Device 100optionally includes one or more tactile output generators 167 forgenerating tactile outputs on device 100 (e.g., generating tactileoutputs on a touch-sensitive surface such as touch-sensitive displaysystem 112 of device 100 or touchpad 355 of device 300). Thesecomponents optionally communicate over one or more communication busesor signal lines 103.

As used in the specification and claims, the term “intensity” of acontact on a touch-sensitive surface refers to the force or pressure(force per unit area) of a contact (e.g., a finger contact) on the touchsensitive surface, or to a substitute (proxy) for the force or pressureof a contact on the touch sensitive surface. The intensity of a contacthas a range of values that includes at least four distinct values andmore typically includes hundreds of distinct values (e.g., at least256). Intensity of a contact is, optionally, determined (or measured)using various approaches and various sensors or combinations of sensors.For example, one or more force sensors underneath or adjacent to thetouch-sensitive surface are, optionally, used to measure force atvarious points on the touch-sensitive surface. In some implementations,force measurements from multiple force sensors are combined (e.g., aweighted average) to determine an estimated force of a contact.Similarly, a pressure-sensitive tip of a stylus is, optionally, used todetermine a pressure of the stylus on the touch-sensitive surface.Alternatively, the size of the contact area detected on thetouch-sensitive surface and/or changes thereto, the capacitance of thetouch-sensitive surface proximate to the contact and/or changes thereto,and/or the resistance of the touch-sensitive surface proximate to thecontact and/or changes thereto are, optionally, used as a substitute forthe force or pressure of the contact on the touch-sensitive surface. Insome implementations, the substitute measurements for contact force orpressure are used directly to determine whether an intensity thresholdhas been exceeded (e.g., the intensity threshold is described in unitscorresponding to the substitute measurements). In some implementations,the substitute measurements for contact force or pressure are convertedto an estimated force or pressure and the estimated force or pressure isused to determine whether an intensity threshold has been exceeded(e.g., the intensity threshold is a pressure threshold measured in unitsof pressure).

As used in the specification and claims, the term “tactile output”refers to physical displacement of a device relative to a previousposition of the device, physical displacement of a component (e.g., atouch-sensitive surface) of a device relative to another component(e.g., housing) of the device, or displacement of the component relativeto a center of mass of the device that will be detected by a user withthe user's sense of touch. For example, in situations where the deviceor the component of the device is in contact with a surface of a userthat is sensitive to touch (e.g., a finger, palm, or other part of auser's hand), the tactile output generated by the physical displacementwill be interpreted by the user as a tactile sensation corresponding toa perceived change in physical characteristics of the device or thecomponent of the device. For example, movement of a touch-sensitivesurface (e.g., a touch-sensitive display or trackpad) is, optionally,interpreted by the user as a “down click” or “up click” of a physicalactuator button. In some cases, a user will feel a tactile sensationsuch as an “down click” or “up click” even when there is no movement ofa physical actuator button associated with the touch-sensitive surfacethat is physically pressed (e.g., displaced) by the user's movements. Asanother example, movement of the touch-sensitive surface is, optionally,interpreted or sensed by the user as “roughness” of the touch-sensitivesurface, even when there is no change in smoothness of thetouch-sensitive surface. While such interpretations of touch by a userwill be subject to the individualized sensory perceptions of the user,there are many sensory perceptions of touch that are common to a largemajority of users. Thus, when a tactile output is described ascorresponding to a particular sensory perception of a user (e.g., an “upclick,” a “down click,” “roughness”), unless otherwise stated, thegenerated tactile output corresponds to physical displacement of thedevice or a component thereof that will generate the described sensoryperception for a typical (or average) user.

In some embodiments, the software components stored in memory 102include operating system 126, communication module (or set ofinstructions) 128, contact/motion module (or set of instructions) 130,graphics module (or set of instructions) 132, text input module (or setof instructions) 134, Global Positioning System (GPS) module (or set ofinstructions) 135, and applications (or sets of instructions) 136.Furthermore, in some embodiments memory 102 stores device/globalinternal state 157, as shown in FIGS. 1A and 3. Device/global internalstate 157 includes one or more of: active application state, indicatingwhich applications, if any, are currently active; display state,indicating what applications, views or other information occupy variousregions of touch screen display 112; sensor state, including informationobtained from the device's various sensors and input control devices116; and location information concerning the device's location and/orattitude.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, oran embedded operating system such as VxWorks) includes various softwarecomponents and/or drivers for controlling and managing general systemtasks (e.g., memory management, storage device control, powermanagement, etc.) and facilitates communication between various hardwareand software components.

Communication module 128 facilitates communication with other devicesover one or more external ports 124 and also includes various softwarecomponents for handling data received by RF circuitry 108 and/orexternal port 124. External port 124 (e.g., Universal Serial Bus (USB),FIREWIRE, etc.) is adapted for coupling directly to other devices orindirectly over a network (e.g., the Internet, wireless LAN, etc.). Insome embodiments, the external port is a multi-pin (e.g., 30-pin)connector that is the same as, or similar to and/or compatible with the30-pin connector used on iPod (trademark of Apple Inc.) devices.

Contact/motion module 130 optionally detects contact with touch screen112 (in conjunction with display controller 156) and other touchsensitive devices (e.g., a touchpad or physical click wheel).Contact/motion module 130 includes various software components forperforming various operations related to detection of contact, such asdetermining if contact has occurred (e.g., detecting a finger-downevent), determining an intensity of the contact (e.g., the force orpressure of the contact or a substitute for the force or pressure of thecontact), determining if there is movement of the contact and trackingthe movement across the touch-sensitive surface (e.g., detecting one ormore finger-dragging events), and determining if the contact has ceased(e.g., detecting a finger-up event or a break in contact).Contact/motion module 130 receives contact data from the touch-sensitivesurface. Determining movement of the point of contact, which isrepresented by a series of contact data, optionally includes determiningspeed (magnitude), velocity (magnitude and direction), and/or anacceleration (a change in magnitude and/or direction) of the point ofcontact. These operations are, optionally, applied to single contacts(e.g., one finger contacts) or to multiple simultaneous contacts (e.g.,“multitouch”/multiple finger contacts). In some embodiments,contact/motion module 130 and display controller 156 detect contact on atouchpad.

In some embodiments, contact/motion module 130 uses a set of one or moreintensity thresholds to determine whether an operation has beenperformed by a user (e.g., to determine whether a user has “clicked” onan icon). In some embodiments at least a subset of the intensitythresholds are determined in accordance with software parameters (e.g.,the intensity thresholds are not determined by the activation thresholdsof particular physical actuators and can be adjusted without changingthe physical hardware of device 100). For example, a mouse “click”threshold of a trackpad or touch screen display can be set to any of alarge range of predefined thresholds values without changing thetrackpad or touch screen display hardware. Additionally, in someimplementations a user of the device is provided with software settingsfor adjusting one or more of the set of intensity thresholds, byadjusting individual intensity thresholds and/or by adjusting aplurality of intensity thresholds at once with a system-level click“intensity” parameter).

Contact/motion module 130 optionally detects a gesture input by a user.Different gestures on the touch-sensitive surface have different contactpatterns (e.g., different motions, timings, and/or intensities ofdetected contacts). Thus, a gesture is, optionally, detected bydetecting a particular contact pattern. For example, detecting a fingertap gesture includes detecting a finger-down event followed by detectinga finger-up (lift off) event at the same position (or substantially thesame position) as the finger-down event (e.g., at the position of anicon). As another example, detecting a finger swipe gesture on thetouch-sensitive surface includes detecting a finger-down event followedby detecting one or more finger-dragging events, and subsequentlyfollowed by detecting a finger-up (lift off) event.

Each of the above identified modules and applications correspond to aset of executable instructions for performing one or more functionsdescribed above and the methods described in this application (e.g., thecomputer-implemented methods and other information processing methodsdescribed herein). These modules (i.e., sets of instructions) need notbe implemented as separate software programs, procedures or modules, andthus various subsets of these modules are, optionally, combined orotherwise re-arranged in various embodiments. In some embodiments,memory 102 optionally stores a subset of the modules and data structuresidentified above. Furthermore, memory 102 optionally stores additionalmodules and data structures not described above.

In some embodiments, device 100 is a device where operation of apredefined set of functions on the device is performed exclusivelythrough a touch screen and/or a touchpad. By using a touch screen and/ora touchpad as the primary input control device for operation of device100, the number of physical input control devices (such as push buttons,dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through atouch screen and/or a touchpad optionally include navigation betweenuser interfaces. In some embodiments, the touchpad, when touched by theuser, navigates device 100 to a main, home, or root menu from any userinterface that is displayed on device 100. In such embodiments, a “menubutton” is implemented using a touchpad. In some other embodiments, themenu button is a physical push button or other physical input controldevice instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for eventhandling in accordance with some embodiments. In some embodiments,memory 102 (in FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g.,in operating system 126) and a respective application 136-1 (e.g., anyof the aforementioned applications 137-13, 155, 380-390).

Event sorter 170 receives event information and determines theapplication 136-1 and application view 191 of application 136-1 to whichto deliver the event information. Event sorter 170 includes eventmonitor 171 and event dispatcher module 174. In some embodiments,application 136-1 includes application internal state 192, whichindicates the current application view(s) displayed on touch sensitivedisplay 112 when the application is active or executing. In someembodiments, device/global internal state 157 is used by event sorter170 to determine which application(s) is (are) currently active, andapplication internal state 192 is used by event sorter 170 to determineapplication views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additionalinformation, such as one or more of: resume information to be used whenapplication 136-1 resumes execution, user interface state informationthat indicates information being displayed or that is ready for displayby application 136-1, a state queue for enabling the user to go back toa prior state or view of application 136-1, and a redo/undo queue ofprevious actions taken by the user.

Event monitor 171 receives event information from peripherals interface118. Event information includes information about a sub-event (e.g., auser touch on touch-sensitive display 112, as part of a multi-touchgesture). Peripherals interface 118 transmits information it receivesfrom I/O subsystem 106 or a sensor, such as proximity sensor 166,accelerometer(s) 168, and/or microphone 113 (through audio circuitry110). Information that peripherals interface 118 receives from I/Osubsystem 106 includes information from touch-sensitive display 112 or atouch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripheralsinterface 118 at predetermined intervals. In response, peripheralsinterface 118 transmits event information. In other embodiments,peripheral interface 118 transmits event information only when there isa significant event (e.g., receiving an input above a predeterminednoise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit viewdetermination module 172 and/or an active event recognizer determinationmodule 173.

Hit view determination module 172 provides software procedures fordetermining where a sub-event has taken place within one or more views,when touch sensitive display 112 displays more than one view. Views aremade up of controls and other elements that a user can see on thedisplay.

Another aspect of the user interface associated with an application is aset of views, sometimes herein called application views or userinterface windows, in which information is displayed and touch-basedgestures occur. The application views (of a respective application) inwhich a touch is detected optionally correspond to programmatic levelswithin a programmatic or view hierarchy of the application. For example,the lowest level view in which a touch is detected is, optionally,called the hit view, and the set of events that are recognized as properinputs are, optionally, determined based, at least in part, on the hitview of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related tosub-events of a touch-based gesture. When an application has multipleviews organized in a hierarchy, hit view determination module 172identifies a hit view as the lowest view in the hierarchy which shouldhandle the sub-event. In most circumstances, the hit view is the lowestlevel view in which an initiating sub-event occurs (i.e., the firstsub-event in the sequence of sub-events that form an event or potentialevent). Once the hit view is identified by the hit view determinationmodule, the hit view typically receives all sub-events related to thesame touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which viewor views within a view hierarchy should receive a particular sequence ofsub-events. In some embodiments, active event recognizer determinationmodule 173 determines that only the hit view should receive a particularsequence of sub-events. In other embodiments, active event recognizerdetermination module 173 determines that all views that include thephysical location of a sub-event are actively involved views, andtherefore determines that all actively involved views should receive aparticular sequence of sub-events. In other embodiments, even if touchsub-events were entirely confined to the area associated with oneparticular view, views higher in the hierarchy would still remain asactively involved views.

Event dispatcher module 174 dispatches the event information to an eventrecognizer (e.g., event recognizer 180). In embodiments including activeevent recognizer determination module 173, event dispatcher module 174delivers the event information to an event recognizer determined byactive event recognizer determination module 173. In some embodiments,event dispatcher module 174 stores in an event queue the eventinformation, which is retrieved by a respective event receiver module182.

In some embodiments, operating system 126 includes event sorter 170.Alternatively, application 136-1 includes event sorter 170. In yet otherembodiments, event sorter 170 is a stand-alone module, or a part ofanother module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of eventhandlers 190 and one or more application views 191, each of whichincludes instructions for handling touch events that occur within arespective view of the application's user interface. Each applicationview 191 of the application 136-1 includes one or more event recognizers180. Typically, a respective application view 191 includes a pluralityof event recognizers 180. In other embodiments, one or more of eventrecognizers 180 are part of a separate module, such as a user interfacekit (not shown) or a higher level object from which application 136-1inherits methods and other properties. In some embodiments, a respectiveevent handler 190 includes one or more of: data updater 176, objectupdater 177, GUI updater 178, and/or event data 179 received from eventsorter 170. Event handler 190 optionally utilizes or calls data updater176, object updater 177 or GUI updater 178 to update the applicationinternal state 192. Alternatively, one or more of the application views191 includes one or more respective event handlers 190. Also, in someembodiments, one or more of data updater 176, object updater 177, andGUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g.,event data 179) from event sorter 170, and identifies an event from theevent information. Event recognizer 180 includes event receiver 182 andevent comparator 184. In some embodiments, event recognizer 180 alsoincludes at least a subset of: metadata 183, and event deliveryinstructions 188 (which optionally include sub-event deliveryinstructions).

Event receiver 182 receives event information from event sorter 170. Theevent information includes information about a sub-event, for example, atouch or a touch movement. Depending on the sub-event, the eventinformation also includes additional information, such as location ofthe sub-event. When the sub-event concerns motion of a touch, the eventinformation optionally also includes speed and direction of thesub-event. In some embodiments, events include rotation of the devicefrom one orientation to another (e.g., from a portrait orientation to alandscape orientation, or vice versa), and the event informationincludes corresponding information about the current orientation (alsocalled device attitude) of the device.

Event comparator 184 compares the event information to predefined eventor sub-event definitions and, based on the comparison, determines anevent or sub-event, or determines or updates the state of an event orsub-event. In some embodiments, event comparator 184 includes eventdefinitions 186. Event definitions 186 contain definitions of events(e.g., predefined sequences of sub-events), for example, event 1(187-1), event 2 (187-2), and others. In some embodiments, sub-events inan event 187 include, for example, touch begin, touch end, touchmovement, touch cancellation, and multiple touching. In one example, thedefinition for event 1 (187-1) is a double tap on a displayed object.The double tap, for example, comprises a first touch (touch begin) onthe displayed object for a predetermined phase, a first lift-off (touchend) for a predetermined phase, a second touch (touch begin) on thedisplayed object for a predetermined phase, and a second lift-off (touchend) for a predetermined phase. In another example, the definition forevent 2 (187-2) is a dragging on a displayed object. The dragging, forexample, comprises a touch (or contact) on the displayed object for apredetermined phase, a movement of the touch across touch-sensitivedisplay 112, and lift-off of the touch (touch end). In some embodiments,the event also includes information for one or more associated eventhandlers 190.

In some embodiments, event definition 187 includes a definition of anevent for a respective user-interface object. In some embodiments, eventcomparator 184 performs a hit test to determine which user-interfaceobject is associated with a sub-event. For example, in an applicationview in which three user-interface objects are displayed ontouch-sensitive display 112, when a touch is detected on touch-sensitivedisplay 112, event comparator 184 performs a hit test to determine whichof the three user-interface objects is associated with the touch(sub-event). If each displayed object is associated with a respectiveevent handler 190, the event comparator uses the result of the hit testto determine which event handler 190 should be activated. For example,event comparator 184 selects an event handler associated with thesub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 alsoincludes delayed actions that delay delivery of the event informationuntil after it has been determined whether the sequence of sub-eventsdoes or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series ofsub-events do not match any of the events in event definitions 186, therespective event recognizer 180 enters an event impossible, eventfailed, or event ended state, after which it disregards subsequentsub-events of the touch-based gesture. In this situation, other eventrecognizers, if any, that remain active for the hit view continue totrack and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata183 with configurable properties, flags, and/or lists that indicate howthe event delivery system should perform sub-event delivery to activelyinvolved event recognizers. In some embodiments, metadata 183 includesconfigurable properties, flags, and/or lists that indicate how eventrecognizers interact, or are enabled to interact, with one another. Insome embodiments, metadata 183 includes configurable properties, flags,and/or lists that indicate whether sub-events are delivered to varyinglevels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates eventhandler 190 associated with an event when one or more particularsub-events of an event are recognized. In some embodiments, a respectiveevent recognizer 180 delivers event information associated with theevent to event handler 190. Activating an event handler 190 is distinctfrom sending (and deferred sending) sub-events to a respective hit view.In some embodiments, event recognizer 180 throws a flag associated withthe recognized event, and event handler 190 associated with the flagcatches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-eventdelivery instructions that deliver event information about a sub-eventwithout activating an event handler. Instead, the sub-event deliveryinstructions deliver event information to event handlers associated withthe series of sub-events or to actively involved views. Event handlersassociated with the series of sub-events or with actively involved viewsreceive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used inapplication 136-1. For example, data updater 176 updates the telephonenumber used in contacts module 137, or stores a video file used in videoplayer module 145. In some embodiments, object updater 177 creates andupdates objects used in application 136-1. For example, object updater176 creates a new user-interface object or updates the position of auser-interface object. GUI updater 178 updates the GUI. For example, GUIupdater 178 prepares display information and sends it to graphics module132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to dataupdater 176, object updater 177, and GUI updater 178. In someembodiments, data updater 176, object updater 177, and GUI updater 178are included in a single module of a respective application 136-1 orapplication view 191. In other embodiments, they are included in two ormore software modules.

It shall be understood that the foregoing discussion regarding eventhandling of user touches on touch-sensitive displays also applies toother forms of user inputs to operate multifunction devices 100 withinput-devices, not all of which are initiated on touch screens. Forexample, mouse movement and mouse button presses, optionally coordinatedwith single or multiple keyboard presses or holds; contact movementssuch as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs;movement of the device; oral instructions; detected eye movements;biometric inputs; and/or any combination thereof are optionally utilizedas inputs corresponding to sub-events which define an event to berecognized.

FIG. 2 illustrates a portable multifunction device 100 having a touchscreen 112 in accordance with some embodiments. The touch screenoptionally displays one or more graphics within user interface (UI) 200.In this embodiment, as well as others described below, a user is enabledto select one or more of the graphics by making a gesture on thegraphics, for example, with one or more fingers 202 (not drawn to scalein the figure) or one or more styluses 203 (not drawn to scale in thefigure). In some embodiments, selection of one or more graphics occurswhen the user breaks contact with the one or more graphics. In someembodiments, the gesture optionally includes one or more taps, one ormore swipes (from left to right, right to left, upward and/or downward)and/or a rolling of a finger (from right to left, left to right, upwardand/or downward) that has made contact with device 100. In someimplementations or circumstances, inadvertent contact with a graphicdoes not select the graphic. For example, a swipe gesture that sweepsover an application icon optionally does not select the correspondingapplication when the gesture corresponding to selection is a tap.

Device 100 optionally also includes one or more physical buttons, suchas “home” or menu button 204. As described previously, menu button 204is, optionally, used to navigate to any application 136 in a set ofapplications that are, optionally executed on device 100. Alternatively,in some embodiments, the menu button is implemented as a soft key in aGUI displayed on touch screen 112.

In one embodiment, device 100 includes touch screen 112, menu button204, push button 206 for powering the device on/off and locking thedevice, volume adjustment button(s) 208, Subscriber Identity Module(SIM) card slot 210, head set jack 212, and docking/charging externalport 124. Push button 206 is, optionally, used to turn the power on/offon the device by depressing the button and holding the button in thedepressed state for a predefined time interval; to lock the device bydepressing the button and releasing the button before the predefinedtime interval has elapsed; and/or to unlock the device or initiate anunlock process. In an alternative embodiment, device 100 also acceptsverbal input for activation or deactivation of some functions throughmicrophone 113. Device 100 also, optionally, includes one or morecontact intensity sensors 165 for detecting intensity of contacts ontouch screen 112 and/or one or more tactile output generators 167 forgenerating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with adisplay and a touch-sensitive surface in accordance with someembodiments. Device 300 need not be portable. In some embodiments,device 300 is a laptop computer, a desktop computer, a tablet computer,a multimedia player device, a navigation device, an educational device(such as a child's learning toy), a gaming system, or a control device(e.g., a home or industrial controller). Device 300 typically includesone or more processing units (CPU's) 310, one or more network or othercommunications interfaces 360, memory 370, and one or more communicationbuses 320 for interconnecting these components. Communication buses 320optionally include circuitry (sometimes called a chipset) thatinterconnects and controls communications between system components.Device 300 includes input/output (I/O) interface 330 comprising display340, which is typically a touch screen display. I/O interface 330 alsooptionally includes a keyboard and/or mouse (or other pointing device)350 and touchpad 355, tactile output generator 357 for generatingtactile outputs on device 300 (e.g., similar to tactile outputgenerator(s) 167 described above with reference to FIG. 1A), sensors 359(e.g., optical, acceleration, proximity, touch-sensitive, and/or contactintensity sensors similar to contact intensity sensor(s) 165 describedabove with reference to FIG. 1A). Memory 370 includes high-speed randomaccess memory, such as DRAM, SRAM, DDR RAM or other random access solidstate memory devices; and optionally includes non-volatile memory, suchas one or more magnetic disk storage devices, optical disk storagedevices, flash memory devices, or other non-volatile solid state storagedevices. Memory 370 optionally includes one or more storage devicesremotely located from CPU(s) 310. In some embodiments, memory 370 storesprograms, modules, and data structures analogous to the programs,modules, and data structures stored in memory 102 of portablemultifunction device 100 (FIG. 1A), or a subset thereof. Furthermore,memory 370 optionally stores additional programs, modules, and datastructures not present in memory 102 of portable multifunction device100. For example, memory 370 of device 300 optionally stores drawingmodule 380, presentation module 382, word processing module 384, websitecreation module 386, disk authoring module 388, and/or spreadsheetmodule 390, while memory 102 of portable multifunction device 100 (FIG.1A) optionally does not store these modules.

Each of the above identified elements in FIG. 3 are, optionally, storedin one or more of the previously mentioned memory devices. Each of theabove identified modules corresponds to a set of instructions forperforming a function described above. The above identified modules orprograms (i.e., sets of instructions) need not be implemented asseparate software programs, procedures or modules, and thus varioussubsets of these modules are, optionally, combined or otherwisere-arranged in various embodiments. In some embodiments, memory 370optionally stores a subset of the modules and data structures identifiedabove. Furthermore, memory 370 optionally stores additional modules anddata structures not described above.

Attention is now directed towards embodiments of user interfaces (“UI”)that is, optionally, implemented on portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu ofapplications on portable multifunction device 100 in accordance withsome embodiments. Similar user interfaces are, optionally, implementedon device 300. In some embodiments, user interface 400 includes thefollowing elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),        such as cellular and Wi-Fi signals;    -   Time 404;    -   Bluetooth indicator 405;    -   Battery status indicator 406;    -   Tray 408 with icons for frequently used applications, such as:        -   Icon 416 for telephone module 138, labeled “Phone,” which            optionally includes an indicator 414 of the number of missed            calls or voicemail messages;        -   Icon 418 for e-mail client module 140, labeled “Mail,” which            optionally includes an indicator 410 of the number of unread            e-mails;        -   Icon 420 for browser module 147, labeled “Browser;” and        -   Icon 422 for video and music player module 152, also            referred to as iPod (trademark of Apple Inc.) module 152,            labeled “iPod;” and    -   Icons for other applications, such as:        -   Icon 424 for IM module 141, labeled “Text;”        -   Icon 426 for calendar module 148, labeled “Calendar;”        -   Icon 428 for image management module 144, labeled “Photos;”        -   Icon 430 for camera module 143, labeled “Camera;”        -   Icon 432 for online video module 155, labeled “Online Video”        -   Icon 434 for stocks widget 149-2, labeled “Stocks;”        -   Icon 436 for map module 154, labeled “Map;”        -   Icon 438 for weather widget 149-1, labeled “Weather;”        -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”        -   Icon 442 for workout support module 142, labeled “Workout            Support;”        -   Icon 444 for notes module 153, labeled “Notes;” and        -   Icon 446 for a settings application or module, which            provides access to settings for device 100 and its various            applications 136.

It should be noted that the icon labels illustrated in FIG. 4A aremerely exemplary. For example, icon 422 for video and music playermodule 152 are labeled “Music” or “Music Player.” Other labels are,optionally, used for various application icons. In some embodiments, alabel for a respective application icon includes a name of anapplication corresponding to the respective application icon. In someembodiments, a label for a particular application icon is distinct froma name of an application corresponding to the particular applicationicon.

FIG. 4B illustrates an exemplary user interface on a device (e.g.,device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tabletor touchpad 355, FIG. 3) that is separate from the display 450 (e.g.,touch screen display 112). Device 300 also, optionally, includes one ormore contact intensity sensors (e.g., one or more of sensors 357) fordetecting intensity of contacts on touch-sensitive surface 451 and/orone or more tactile output generators 359 for generating tactile outputsfor a user of device 300.

Although some of the examples which follow will be given with referenceto inputs on touch screen display 112 (where the touch sensitive surfaceand the display are combined), in some embodiments, the device detectsinputs on a touch-sensitive surface that is separate from the display,as shown in FIG. 4B. In some embodiments the touch sensitive surface(e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) thatcorresponds to a primary axis (e.g., 453 in FIG. 4B) on the display(e.g., 450). In accordance with these embodiments, the device detectscontacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface451 at locations that correspond to respective locations on the display(e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470).In this way, user inputs (e.g., contacts 460 and 462, and movementsthereof) detected by the device on the touch-sensitive surface (e.g.,451 in FIG. 4B) are used by the device to manipulate the user interfaceon the display (e.g., 450 in FIG. 4B) of the multifunction device whenthe touch-sensitive surface is separate from the display. It should beunderstood that similar methods are, optionally, used for other userinterfaces described herein.

Additionally, while the following examples are given primarily withreference to finger inputs (e.g., finger contacts, finger tap gestures,finger swipe gestures), it should be understood that, in someembodiments, one or more of the finger inputs are replaced with inputfrom another input device (e.g., a mouse based input or stylus input).For example, a swipe gesture is, optionally, replaced with a mouse click(e.g., instead of a contact) followed by movement of the cursor alongthe path of the swipe (e.g., instead of movement of the contact). Asanother example, a tap gesture is, optionally, replaced with a mouseclick while the cursor is located over the location of the tap gesture(e.g., instead of detection of the contact followed by ceasing to detectthe contact). Similarly, when multiple user inputs are simultaneouslydetected, it should be understood that multiple computer mice are,optionally, used simultaneously, or a mouse and finger contacts are,optionally, used simultaneously.

User Interfaces and Associated Processes

Attention is now directed towards embodiments of user interfaces (“UI”)and associated processes that may be implemented on an electronic devicewith a display, a touch-sensitive surface, and a camera, such as device300 or portable multifunction device 100.

FIGS. 5A-5N illustrate exemplary user interfaces for switching betweencamera interfaces in accordance with some embodiments. The userinterfaces in these figures are used to illustrate the processesdescribed below, including the processes in FIGS. 6A-6G.

FIG. 5A illustrates camera interface 502-1 being displayed on touchscreen 112. Camera interface 502-1 is one of multiple interfaces 502 fora camera application (e.g., camera module 143). Each of the interfacescorresponds to a virtual camera or a camera mode. For example, camerainterface 502-1 corresponds to a standard camera mode or a virtualstandard camera.

Camera interface 502-1 includes camera roll icon 504, shutter button506-1, camera preview 508-1, and one or more controls. The controlsinclude, for example, flash control510, high-dynamic-range (HDR)control512, grid control514, filters control516, and front/back cameracontrol 518. Device 100 displays a camera roll (e.g., a set of picturesand videos captured by the camera on device 100) in response toactivation of camera roll icon 504. Activation of flash control 510activates display of a set of flash options (e.g., on, off, automatic)for user selection on touch screen 112. Activation of HDR control 512toggles high dynamic range functionality for camera interface 502-1.Activation of grid control 514 toggles display of grid lines on camerapreview 508-1. Activation of filters control516 activates display of aset of filter options 556 (FIG. 5L) for user selection on touch screen112. Activation of front/back camera control 518 toggles betweenactivating a back-facing camera on device 100 and activating afront-facing camera on device 100.

Camera preview 508 displays visual data sensed by the camera on device100. Camera preview 508 gives the user a preview of what would beincluded in media captured by the camera on device 100.

FIG. 5A shows device 100 detecting gesture (e.g., a tap-and-holdgesture) with contact 520, at location 520-a on camera preview 508-1. Inresponse to detecting the gesture with contact 520, device 100 displaysmagnified area (which can also be referred to as an “autofocus loupe”)522 at location 522-a in proximity to contact 520 at location 520-a, asshown in FIG. 5B. Within autofocus loupe 522, a zoom-in view of thevicinity of contact 520 is displayed. Point 524-1 on the zoom-in view inautofocus loupe 522 (e.g., a point corresponding to the center ofmagnified area 522) is selected as an autofocus reference point.

FIGS. 5B-5C shows contact 520, while still maintaining contact withtouch screen 112, moving in direction 526 to location 520-b. In responseto detecting the movement of contact 520, device 100 moves autofocusloupe 522 to location 522-b in proximity to contact 520 at location520-b, as shown in FIG. 5C. Point 524-2 on the zoom-in view in autofocusloupe 522 (e.g., a point corresponding to the center of autofocus loupe522) is selected as the new autofocus reference point.

In some embodiments, when a contact is detected on touch screen 112, theinput made with the contact activates either display of autofocus loupe522 and selection of an autofocus reference point, or switching from thecurrently displayed camera interface 502 to another camera interface502. In some embodiments, a criterion for determining which of the twooperations to activate is whether the contact moves by more than apredefined amount on touch screen 112 within a predefined time period.If the contact is stationary or substantially stationary for thepredefined time period from contact with touch screen 112 (e.g., contact520 in Figure SA), then autofocus loupe 522 is displayed and anautofocus reference point is selected.

On the other hand, if the contact moves within the predefined timeperiod from contact with touch screen 112, then device 100 switches thecurrently displayed camera interface 502 to another camera interface502. For example, FIG. 5D shows a gesture (e.g. a swipe gesture) withcontact 528 detected at location 528-a on touch screen 112. The gestureincludes contact 528 moving in direction 530 to location 528-b (FIG. 5E)and beyond. Contact 528 moves within the predefined time period fromcontact with touch screen 112. The gesture does not interact with anycamera interface-switching affordance. Further, contact 528, in itsmovement, moves over camera preview 508-1, and does not move over anydisplayed affordance for controlling operation of the camera (e.g.,camera roll icon 504; shutter button 506-1; controls 510, 512, 514, 516,and 518). In response to detecting the movement of contact 528, device100 switches from camera interface 502-1 to camera interface 502-2, asshown in FIGS. 5E-5H.

In some embodiments, the switching of the camera interfaces includes ananimation showing the transition from one interface to the other. Insome embodiments, the animation depicts a lens switch effect. Theanimation includes, for example, displaying of respective blurredimages, which correspond to visual data recently detected by the camera(e.g., visual data that was last shown in camera preview 508 prior tothe animation), associated with the interface being switched out and theinterface being switched in. The animation also includes, for example,translation of the blurred image associated with the switched-out camerainterface off of the display and translation of the blurred imageassociated with the switched-in camera interface onto the display.

Thus, for example, FIG. 5E shows blurred image 532-1, which isassociated with camera interface 502-1, displayed on touch screen 112.As contact 528 continues moving in direction 530, blurred image 532-1translates off touch screen in direction 530, and blurred image 532-2,which is associated with camera interface 502-2, translates onto touchscreen 112 in direction 530. FIGS. 5F-5G show, as contact continuesmovement in direction 520 to locations 528-c and 528-d, blurred image532-1 continues translating off touch screen 112 and blurred image 532-2continues translating onto touch screen 112.

FIG. 5H shows the completion of the animation, with camera interface502-2 displayed on touch screen 112, replacing camera interface 502-1.Camera interface 502-2 corresponds to a video camera mode or a virtualvideo camera. Camera interface 502-2 includes camera roll icon 504,shutter (e.g., video recording on/off) button 506-2, camera preview508-2, and permanent flash control534. Activation of permanent flashcontrol534 toggles between turning the flash light off and permanentlyturning the flash light.

Camera interface 502-1 and camera interface 502-2 captures media withdifferent output dimensions and different aspect ratios. In someembodiments, camera interface 502-1 captures still images withdimensions matching the sensor dimensions of the physical camera sensorson device 100 (e.g., 3264×2448 pixels) and a corresponding aspect ratio(e.g., 4:3), and camera interface 502-2 captures video with dimensionssmaller than the sensor dimensions of the physical camera sensors (e.g.,smaller than 3264×2448 pixels) and at a different aspect ratio (e.g.,16:9).

Camera previews 508-1 and 508-2, corresponding to camera interfaces502-1 and 502-2, respectively, include respective visual indications ofthe output dimensions associated with the respective camera interfaces.For example, camera preview 508-1 (FIG. 5A) is displayed with noletterboxing, indicating that the output dimensions for camera interface502-1 match the sensor dimensions. Camera preview 508-2 (FIG. 5H) isdisplayed with letterboxing, indicating that the output dimensions forcamera interface 502-2 is smaller than the sensor dimensions.

In some embodiments, camera interface 502-1 includes one or morecontrols that are not included in camera interface 502-2. In someembodiments, camera interface 502-2 includes one or more controls thatare not included in camera interface 502-1. For example, camerainterface 502-1 includes HDR control512 that is not included in camerainterface 502-2, and camera interface 502-2 includes permanent flashcontrol 534 that is not included in camera interface 502-1.

FIG. 5H shows a gesture (e.g., a swipe gesture) with contact 536detected by device 100 on touch screen 112 over camera preview 508-2.The gesture includes contact 536 moving across camera preview 508-2, andnot across any displayed affordance for controlling operation of thecamera, in direction 540, which is opposite of direction 530. Inresponse to detecting the gesture with contact 536, device 100 switchesfrom camera interface 502-2 back to camera interface 502-1. In someembodiments, an animation similar to the animation depicted in FIGS.5E-5G, but in the reverse direction as that shown in FIGS. 5E-5G, isdisplayed for the switch from camera interface 502-2 to camera interface502-1.

FIG. 5H also shows, alternatively, a gesture (e.g., a swipe gesture)with contact 538 detected by device 100 on touch screen 112 over camerapreview 508-2. The gesture includes contact 538 moving across camerapreview 508-2, and not across any displayed affordance for controllingoperation of the camera, in direction 530. In response to detecting thegesture with contact 538, device 100 switches from camera interface502-2 to camera interface 502-3 (FIG. 51). In some embodiments, ananimation similar to the animation depicted in FIGS. 5E-5G is displayedfor the switch from camera interface 502-2 to camera interface 502-3.

FIG. 51 shows camera interface 502-3 displayed on touch screen 112.Camera interface 502-3 corresponds to a square camera mode or a virtualsquare camera. Camera interface 502-3 includes camera roll icon 504,shutter button 506-3, camera preview 508-3, flash control 542, andblack-and-white control 544. Flash control 542 is the same as flashcontrol 510 (FIG. 5A). Activation of black-and-white control544 togglesbetween black-and-white image mode and color image mode. Black-and-whitecontrol544 is not included in camera interface 502-1 or camera interface502-2.

Camera interfaces 502-1, 502-2, and 502-3 have one or more controls incommon. For example, camera roll icon 504 is present in camerainterfaces 502-1, 502-2, and 502-3, and is displayed at the samelocation on touch screen 112 in camera interfaces 502-1, 502-2, and502-3. Also, each of camera interfaces 502-1, 502-2, and 502-3 includesa shutter button 506 at the same location on touch screen 112, with thevisual appearance of shutter button 506 varying depending on theparticular interface (e.g., the visual appearance of shutter button506-2 differs from that of shutter button 506-1 or 506-3).

Camera interface 502-3 captures media with different output dimensionsand aspect ratio than camera interfaces 502-1 or 502-2. For example,camera interface 502-3 is associated with smaller output dimensions thanthe sensor dimensions on device 100, and is associated with a 1:1 aspectratio. The windowboxing (i.e., having both letterboxing andpillarboxing) demarcating a square camera preview 508-3, as shown inFIG. 51, provides visual indication of the 1:1 aspect ratio and thesmaller output dimensions.

FIG. 51 shows a gesture (e.g., a swipe gesture) with contact 546detected by device 100 on touch screen 112 over camera preview 508-3.The gesture includes contact 546 moving across camera preview 508-3, andnot across any displayed affordance for controlling operation of thecamera, in direction 540, which is opposite of direction 530. Inresponse to detecting the gesture with contact 546, device 100 switchesfrom camera interface 502-3 back to camera interface 502-2. In someembodiments, an animation similar to the animation depicted in FIGS.5E-5G, but in the reverse direction as that shown in FIGS. 5E-5G, isdisplayed for the switch from camera interface 502-3 to camera interface502-2.

FIG. 51 also shows, alternatively, a gesture (e.g., a swipe gesture)with contact 548 detected by device 100 on touch screen 112 over camerapreview 508-3. The gesture includes contact 548 moving across camerapreview 508-3, and not across any displayed affordance for controllingoperation of the camera, in direction 530. In response to detecting thegesture with contact 548, device 100 switches from camera interface502-3 to camera interface 502-4 (FIG. 51). In some embodiments, ananimation similar to the animation depicted in FIGS. 5E-5G is displayedfor the switch from camera interface 502-3 to camera interface 502-4.

FIG. 51 shows camera interface 502-4 displayed on touch screen 112.Camera interface 502-4 corresponds to a panorama camera mode or avirtual panorama camera. Camera interface 502-4 includes camera rollicon 504, shutter button 506-4, camera preview 508-4, and panoramaprogress indicator 550. Panorama progress indicator 550 displays thealignment of sequential images for a panorama. Camera interfaces 502-1,502-2, 502-3 do not include panorama progress indicator 550. Thus, insome embodiments, the output of the panorama camera is a variable sizeimage that depends on how many images were stitched together into thepanorama and how much the images overlapped and how much the finalpanorama image was cropped.

Camera interfaces 502-1, 502-2, 502-3, and 502-4 have one or morecontrols in common. For example, camera roll icon 504 is present incamera interfaces 502-1, 502-2, 502-3, and 502-4, and is displayed atthe same location on touch screen 112 in camera interfaces 502-1, 502-2,502-3, and 502-4. Also, each of camera interfaces 502-1, 502-2, 502-3,and 502-4 includes a shutter button 506 at the same location on touchscreen 112, with the visual appearance of shutter button 506 varyingdepending on the particular interface (e.g., the visual appearance ofshutter button 506-2 differs from that of shutter button 506-1, 506-3,or 506-4).

Camera interface 502-4 captures media with different output dimensionsand aspect ratio than camera interfaces 502-1, 502-2, or 502-3. Forexample, camera interface 502-4 is associated with larger outputdimensions than the sensor dimensions on device 100, and is associatedwith a different aspect ratio than the aspect ratios associated withcamera interfaces 502-1, 502-2, and 502-3. Panorama progress indicator550 provides visual indication of the different aspect ratio and thelarger output dimensions.

FIG. 51 shows a gesture (e.g., a swipe gesture) with contact 552detected by device 100 on touch screen 112 over camera preview 508-4.The gesture includes contact 552 moving across camera preview 508-4, andnot across any displayed affordance for controlling operation of thecamera, in direction 540, which is opposite of direction 530. Inresponse to detecting the gesture with contact 552, device 100 switchesfrom camera interface 502-4 back to camera interface 502-3. In someembodiments, an animation similar to the animation depicted in FIGS.5E-5G, but in the reverse direction as that shown in FIGS. 5E-5G, isdisplayed for the switch from camera interface 502-4 to camera interface502-3.

Thus, FIGS. 5D-5J illustrate device 100 that switches amongst fourcamera interfaces 502, in sequence, in response to detecting respectivegestures that include movements of contacts across touch screen 112(e.g., across camera preview 508). It should be appreciated that device100 can switch between more than four (e.g., five or more) or less thatfour (e.g., three) camera interfaces 502. Also, the sequence ofinterfaces 502 shown in FIGS. 5D-5J is merely exemplary, and theinterfaces 502 may be ordered in any suitable order.

In some embodiments, device 100 switches between three camera interfaces502 in response to detecting respective gestures. The three interfacesinclude, for example, a video camera interface (e.g., interface 502-2)and two different still image camera interfaces (e.g., interface 502-1and either interface 502-3 or 502-4). In some embodiments, the threeinterfaces include any three of the following: a rectangular stillcamera interface (e.g., interface 502-1), a video camera interface(e.g., interface 502-2), a panorama still camera interface (e.g.,interface 502-4), a black and white still camera interface, and a squarestill camera interface (e.g., interface 502-3).

In some embodiments, the sequence of camera interfaces is configured toinclude three interfaces by default, and additional interfaces beyondthe three are included in accordance with user input. For example, thedefault sequence includes interfaces 502-1, 502-2, and 502-3, and theuser can select interface 502-4 for addition to the sequence.Alternatively, the default sequence includes interfaces 502-1, 502-2,and 502-4, and the user can select interface 502-3 for addition to thesequence.

FIG. 5K shows camera interface 502-1, with camera preview 508-1,displayed on touch screen 112, as in FIG. 5A. Device 100 detects contact554 on filter control 516. In response to detecting contact 554 onfilter control 516, device 100 displays filter options 556 on touchscreen 112, as shown in FIG. 5L. Filter options 556-1 thru 556-3correspond to different filters that are applied to media captured bydevice 100.

Device 100 detects contact 558 on filter option 556-3. In response todetecting contact 558 on filter option 556-3, the filter correspondingto filter option 556-3 is applied to visual data captured by the cameraon device 100. Camera preview 508-1 is displayed with the filterapplied, as shown in FIG. 5M, thus giving the user a live preview of thevisual appearance of media with the filter applied. Optionally, filtercontrol 516 is highlighted (e.g., with a thicker border) to furtherindicate that a filter is being applied.

In some embodiments, camera interface switching controls are displayedon touch screen 112, in the respective interfaces. For example, FIG. 5Nshows camera interface switching controls 560 displayed on touch screen112 in camera interface 502-2. Control 560-1 corresponds to interface502-1, and includes a standard camera icon indicating thecorrespondence. Control560-2 corresponds to interface 502-2, andincludes a video camera icon indicating the correspondence. Control560-3 corresponds to interface 502-3, and includes a square icon (for asquare camera) indicating the correspondence. Control 560-2 ishighlighted (e.g., with a thicker border) to indicate that interface502-3 is currently displayed on touch screen 112. In response todetecting a respective contact on a respective control 560, device 100switches from the currently displayed camera interface to the camerainterface to which the control 560 over which the contact is detectedcorresponds. For example, device 100 detects contact 562 on control560-1. In response to detecting contact 562 over control560-1, device100 switches from camera interface 502-2 to camera interface 502-1.Similarly, in response to detecting a contact over control 560-3, device100 switches from camera interface 502-2 to camera interface 502-3.

FIGS. 6A-6G are flow diagrams illustrating a method 600 of switchingbetween camera interfaces in accordance with some embodiments. Themethod 600 is performed at an electronic device (e.g., device 300, FIG.3, or portable multifunction device 100, FIG. 1A) with a display and atouch-sensitive surface. In some embodiments, the display is a touchscreen display and the touch-sensitive surface is on the display. Insome embodiments, the display is separate from the touch-sensitivesurface. Some operations in method 600 are, optionally, combined and/orthe order of some operations is, optionally, changed.

As described below, the method 600 provides an intuitive way to switchbetween camera interfaces. The method reduces the cognitive burden on auser when switching between camera interfaces, thereby creating a moreefficient human-machine interface. For battery-operated electronicdevices, enabling a user to switch between camera interfaces faster andmore efficiently conserves power and increases the time between batterycharges.

The device displays (602) a first camera interface on the display for afirst virtual camera that produces media with first output dimensions(e.g., dimensions of the media in pixels such as 3264×2448 pixels). Forexample, FIGS. 5A and 5D show camera interface 502-1 displayed on touchscreen 112. Camera interface 502-1 corresponds to a virtual standardcamera that captures still images with certain output dimensions.

While displaying the first camera interface on the display, the devicedetects (604) a first gesture that includes movement of a contact in afirst direction on the touch-sensitive surface, where the first gesturedoes not interact with a predefined camera-switching affordance. In someembodiments, the first camera interface does not include a predefinedcamera-switching affordance. In some embodiments, the first camerainterface includes a predefined camera-switching affordance but thefirst gesture corresponds to a location of the first camera interfacethat does not include (e.g., is remote from) the predefinedcamera-switching affordance. Device 100 detects a gesture with contact528 moving in direction 530, as shown in FIG. 5D for example. Thegesture does not interact with any camera-switching affordance (e.g.,camera interface switching controls 560 (FIG. 5N)).

In some embodiments, the touch-sensitive surface is part of atouchscreen display, and the first gesture includes movement of acontact across a camera preview displayed on the touchscreen display(606). For example, the gesture with contact 528 moves across touchscreen 112 over camera preview 508-1 (FIG. 5D).

In some embodiments, the touch-sensitive surface is part of atouchscreen display, and the first gesture includes movement of acontact across a portion of the touchscreen display that does notinclude any displayed affordances for controlling operation of thecamera (608). For example, the gesture with contact 528 moves acrosstouch screen 112 over camera preview 508-1 (FIG. 5D), and does not moveover any displayed affordance for controlling operation of the camera(e.g., camera roll icon 504; shutter button 506-1; controls 510, 512,514, 516, and 518).

In response to detecting the first gesture, the device switches (610)from displaying the first camera interface to displaying a second camerainterface for a second virtual camera that produces media with secondoutput dimensions different from the first output dimensions, where thesecond camera interface is different from the first camera interface. Insome embodiments, the first camera interface includes at least onerespective control not displayed in the second camera interface, thesecond camera interface includes at least one respective control notdisplayed in the first camera interface, and/or a media preview has adifferent appearance in the first camera interface than in the secondcamera interface. In some embodiments, the one respective control thatis different between the first camera interface and the second camerainterface includes a hardware camera selection button (e.g., frontcamera vs back camera) an image capture options button, a filterselection button, or a flash toggle button. In response to detecting thegesture with contact 528, device 100 switches from camera interface502-1 (FIG. 5D) to camera interface 502-2 (FIG. 5H). Camera interface502-2 corresponds to a virtual video camera and is associated withdifferent output dimensions than camera interface 502-1.

In some embodiments, the first camera interface provides (612) a visualindication of the first output dimensions (e.g., a full screen displayof camera preview for a standard still camera), and the second camerainterface provides a visual indication of the second output dimensions(e.g., a letterboxed camera preview for a square camera or a videocamera). For example, camera preview 508-1 in camera interface 502-1 isa full-screen preview, and camera preview 508-2 in camera interface502-2 is a letterboxed camera preview.

In some embodiments, the first output dimensions have (614) a differentaspect ratio than the second output dimensions. For example, the aspectratio associated with camera interface 502-1 is 4:3, and the aspectratio associated with camera interface 502-2 is 16:9.

In some embodiments, the first camera interface includes (616) one ormore controls that are not included in the second camera interface (and,optionally, a third camera user interface) (e.g., still camera displayoptions or still image capture options such as high dynamic range or“HDR” images that are not available for a video camera or a panoramacamera, etc.). For example, camera interface 502-1 includes HDRcontrol512 that is not included in camera interfaces 502-2, 502-3, or502-4.

In some embodiments, the second camera interface includes (618) one ormore controls that are not included in the first camera interface (and,optionally, the third camera user interface) (e.g., a control forpermanently turning on the flash). For example, camera interface 502-2includes permanent flash control 534 that is not included in camerainterface 502-1, 502-3, or 502-4.

In some embodiments, switching from displaying the first camerainterface to displaying a second camera interface includes displaying(620) an animated transition between the first camera interface and thesecond camera interface. The animated transition includes displaying afirst blurred image that corresponds to visual data recently detected bythe camera, translating the first blurred image off of the display in arespective direction, displaying movement of a boundary across thedisplay in the respective direction, and translating a second blurredimage onto the display in the respective direction, where the secondblurred image corresponds to visual data recently detected by thecamera. In some embodiments, the respective direction corresponds to adirection of movement of the contact on the touch-sensitive surfaceduring the first gesture. In some embodiments, the boundary is curved soas to simulate the movement of an interchangeable lens over the camerasensor. In some embodiments, the first and second blurred imagecorrespond to the same visual data (e.g., data captured with the cameraprior to switching camera user interfaces), because the camera isswitching between different “modes” and is thus not available to capturevisual data corresponding to the mode of operation associated with thesecond camera interface. In some embodiments, a similar animation isdisplayed when switching from the second camera interface to a third,different, camera interface (e.g., a camera interface for a panoramacamera). In some embodiments, the animated transition includesdisplaying a shutter button for the first camera interface transitioningto a shutter button for the second camera interface (e.g., a red shutterbutton for a video camera interface sliding in to replace a gray orsilver shutter button for a still camera interface).

For example, FIGS. 5D-5H show a switch from camera interface 502-1 tocamera interface 502-1 that includes an animation. The animationincludes blurred image 532-1, corresponding to camera interface 502-1,translating off of touch screen 112 in direction 530, and blurred image532-2, corresponding to camera interface 502-2, translating onto touchscreen 112 in direction 530.

In some embodiments, the first camera interface includes a first camerapreview for displaying current visual data being detected by the camera(622). The device receives (624) a request to apply a user-selectedfilter to media captured by the device, and applies (626) theuser-selected filter to visual data captured by the camera, so that thefirst camera preview includes the current visual data modified by theuser-selected filter. In some embodiments, the user-selected filter isapplied to an image or video in response to receiving a request tocapture media (e.g., video or a still image while the user-selectedfilter is selected and is being applied to the camera preview). In someembodiments, the user-selected filter is selected while a prior filter(or no filter) is selected, and the device ceases to display the currentvisual data modified by the prior filter and starts to display thecurrent visual data modified by the user-selected filter (e.g., thefilter is a “live” filter that is applied “live” to a preview of thecamera output). In some embodiments, the filter is a non-destructivefilter that can later be removed from the image (e.g., the image datacaptured by the camera is stored separately from a respective stack ofimage processing operations that are performed on the image data, andthe respective stack of image processing operations can be removed andreplaced with a different stack of image processing operations to removethe filter and/or apply a different filter in response to a user requestto remove the filter and/or apply a different filter).

For example, FIGS. 5K-5L shows device 100 receiving a request (in theform of contact 558 on filter option 556-3) to apply a filtercorresponding to filter option 556-3. In response to receiving therequest, device 100 applies the filter to visual data captured by thecamera; camera preview 508-1 is displayed with the filter applied, asshown in FIG. 5M.

In some embodiments, the touch-sensitive surface includes a touchscreendisplay, and a respective camera interface includes a respective camerapreview for displaying current visual data detected by the camera (628).While displaying the respective camera interface, the device detects(630) a respective input that includes a respective contact detected ata location that corresponds to the respective camera preview (e.g., atouch and hold input corresponding to a respective contact detected onthe touchscreen display). In response to detecting the respective input,displaying (632) a first magnified portion of the respective camerapreview and selecting a point within the first magnified portion as anautofocus reference point. Displaying the first magnified portion (e.g.,an “autofocus loupe”) enables a user to more accurately select anautofocus reference point in the camera preview. For example, FIG. 5Ashows a tap-and-hold gesture with contact 520 detected on touch screen112 over camera preview 508-1. In response to detecting the gesture, azoomed-in portion of camera preview 508-1 is displayed in autofocusloupe 522 on touch screen 112, and point 524-1 in the zoom-in portion isselected as the autofocus reference point.

In some embodiments, while displaying the first magnified portion, thedevice detects (634) movement of the respective contact within thecamera preview. In response to detecting the movement of the respectivecontact, the device displays (636) a second magnified portion of therespective camera preview, different from the first magnified portion,and selecting a point within the second magnified portion as theautofocus reference point. For example, in response to detectingmovement of contact 520 from location 520-a to location 520-b whileautofocus loupe 522 is displayed, device 100 displays autofocus loupe522 at location 522-b, and the zoomed-in portion displayed withinautofocus loupe 522 the zoomed-in portion of camera preview 508-1 in thevicinity of contact 520 at location 520-b. Point 524-2 in the zoomed-inportion is selected as the new autofocus reference point.

In some embodiments, the touch-sensitive surface includes a touchscreendisplay, and the first camera interface includes a respective camerapreview for displaying current visual data detected by the camera (638).While displaying the first camera interface, the device detects (640) arespective input that includes a respective contact detected in therespective camera preview. In response to detecting the respective input(642), the device determines (644) whether input includes movement ofthe respective contact by more than a predefined amount on thetouchscreen display within a predefined time period. In accordance witha determination that the respective input includes movement of therespective contact by more than the predefined amount on the touchscreendisplay within the predefined time period (e.g., the contact moveswithin 0.1, 0.2, 0.5 seconds or some other reasonable time period), thedevice switches (646) from the first camera interface to a differentcamera interface (e.g., displaying different camera interface inresponse to detecting a swipe gesture). In accordance with adetermination that the respective contact does not move by more than thepredefined amount on the touchscreen display within a predefined timeperiod (e.g., the contact is stationary or substantially stationary for0.1, 0.2, 0.5 seconds or some other reasonable time period), the devicedisplays a magnified portion of the respective camera preview andselecting a point within the magnified portion as an autofocus referencepoint (e.g., displaying an autofocus loupe in response to detecting atouch and hold gesture). For example, FIGS. 5A and 50 show contacts 520and 528, respectively, detected on touch screen 112 over camera preview508-1. Contact 520 is substantially stationary for a predefined timeperiod from contact with touch screen 112. Contact 528 moves within thepredefined time period from contact with touch screen 112. In responseto detecting contact 520, autofocus loupe 522 is displayed and point524-1 is selected as an autofocus reference point (FIG. 5B). In responseto detecting contact 528 and its movement, device 100 switches fromcamera interface 502-1 to camera interface 502-2.

In some embodiments, while displaying the second camera interface on thedisplay, the device detects (650) a second gesture on thetouch-sensitive surface. In response to detecting the second gesture(652), in accordance with a determination that the second gestureincludes movement of the contact in the first direction on thetouch-sensitive surface, the device switches (654) from displaying thesecond camera interface to displaying a third camera interface for athird virtual camera that produces media with third output dimensionsdifferent from the first output dimensions and the second outputdimensions (e.g., replacing display of the second camera interface withthe third camera interface), where the third camera interface isdifferent from the first camera interface (e.g., the third camerainterface includes at least one respective control not displayed in thefirst camera interface, the third camera interface includes at least onerespective control not displayed in the first camera interface, and/or amedia preview has a different appearance in the first camera interfacethan in the third camera interface), and the third camera interface isdifferent from the second camera interface (e.g., the third camerainterface includes at least one respective control not displayed in thesecond camera interface, the third camera interface includes at leastone respective control not displayed in the second camera interface,and/or a media preview has a different appearance in the second camerainterface than in the third camera interface). FIG. 5H shows, whilecamera interface 502-2 is displayed, a gesture is detected on touchscreen 112. The gesture includes contact 538 moving on touch screen 112in direction 530, over camera preview 508-2. In response to detectingthe gesture, device 100 switches from camera interface 502-2 to camerainterface 502-3 (FIG. 51). Camera interface 502-3 is different fromcamera interface 502-1 and camera interface 502-2.

In some embodiments, in response to detecting the second gesture (652),in accordance with a determination that the second gesture includesmovement of the contact in a second direction on the touch-sensitivesurface, different from the first direction (e.g. opposite to the firstdirection), the device switches (656) from displaying the second camerainterface to displaying the first camera interface (e.g., replacingdisplay of the second camera interface with the first camera interface).FIG. 5H shows, while camera interface 502-2 is displayed, a gesture isdetected on touch screen 112. The gesture includes contact 536 moving ontouch screen 112 in direction 540, over camera preview 508-2. Inresponse to detecting the gesture, device 100 switches from camerainterface 502-2 to camera interface 502-1 (FIG. 5D).

In some embodiments, the second camera interface includes a control forswitching between camera interfaces that includes a plurality ofgraphical objects, including: a first graphical object that isdescriptive of the first camera interface, a second graphical objectthat is descriptive of the second camera interface, and a thirdgraphical object that is descriptive of the third camera interface(658).

In response to detecting activation of a respective graphical object inthe plurality of graphical objects (660), in accordance with adetermination that the first graphical object was activated, the deviceswitches (662) from displaying the second camera interface to displayingthe first camera interface; and in accordance with a determination thatthe third graphical object was activated, switches (664) from displayingthe second camera interface to displaying the third camera interface. Insome embodiments, a similar control for switching between the camerainterfaces is displayed in the first camera interface and the thirdcamera interface. In some embodiments, the graphical objects changeposition in accordance with a currently displayed camera interface(e.g., the graphical object corresponding to the currently displayedcamera interface is displayed in a middle of the control; a graphicalobject corresponding to a camera interface that would be displayed inresponse to a swipe gesture from right-to-left is displayed on a rightside of the control; and a graphical object corresponding to a camerainterface that would be displayed in response to a swipe gesture fromleft-to-right is displayed on a left side of the control. For example,in FIG. 5N, camera interface 502-2 includes optionally displayed camerainterface switching controls 560. Control560-1 corresponds to camerainterface 502-1. Control 560-2 corresponds to camera interface 502-2.Control 560-3 corresponds to camera interface 502-3. Device 100 switchesto camera interface 502-1 in response to detection of contact 562 oncontrol 560-1. Device 100 switches to camera interface 502-3 in responseto detection of a contact on control 560-3.

In some embodiments, while displaying the third camera interface on thedisplay, the device detects (666) a third gesture on the touch-sensitivesurface. In response to detecting the third gesture, in accordance witha determination that the third gesture includes movement of the contactin the first direction on the touch-sensitive surface, the deviceswitches (668) from displaying the third camera interface to displayinga fourth camera interface for a fourth virtual camera that waspreviously selected, based on prior inputs from the user, to bedisplayed in response to movement of a contact in the first directionwhile the third camera interface is displayed (e.g., the device replacesdisplay of the third camera interface with the fourth camera interfacefor a user-selected virtual camera that was previously selected from aplurality of candidate virtual cameras that are not in a set ofquick-access virtual cameras that are accessible by swiping on thetouch-sensitive surface) In some embodiments, the fourth camerainterface is an interface for a fourth virtual camera that producesmedia with fourth output dimensions different from the first, second,and third output dimensions (e.g., a square virtual camera), where: thefourth camera interface is different from the first camera interface(e.g., the fourth camera interface includes at least one respectivecontrol not displayed in the first camera interface, the fourth camerainterface includes at least one respective control not displayed in thefirst camera interface, and/or a media preview has a differentappearance in the first camera interface than in the fourth camerainterface), the fourth camera interface is different from the secondcamera interface (e.g., the fourth camera interface includes at leastone respective control not displayed in the second camera interface, thefourth camera interface includes at least one respective control notdisplayed in the second camera interface, and/or a media preview has adifferent appearance in the second camera interface than in the fourthcamera interface), and the fourth camera interface is different from thethird camera interface (e.g., the fourth camera interface includes atleast one respective control not displayed in the third camerainterface, the fourth camera interface includes at least one respectivecontrol not displayed in the third camera interface, and/or a mediapreview has a different appearance in the third camera interface than inthe fourth camera interface).

FIG. 51 shows, while camera interface 502-3 is displayed, a gesture isdetected on touch screen 112. The gesture includes contact 548 moving ontouch screen 112 in direction 530, over camera preview 508-3. Inresponse to detecting the gesture, device 100 switches from camerainterface 502-3 to camera interface 502-4 (FIG. 5J). Camera interface502-4 is different from camera interfaces 502-1, 502-2, and 502-3.Camera interface 502-4 was added to the sequence of camera interfaces bythe user.

In some embodiments, the device provides quick access to a set ofquick-access virtual cameras, where the user is enabled to switchthrough the quick-access cameras by performing one or more repetitionsof a simple gesture on the touch-sensitive surface (e.g., a swipegesture). In some embodiments, the device includes one or more standardor default virtual cameras in the set of quick-access virtual cameras.For example, the device includes an “ordinary” oblong rectangular stillcamera, a video camera and a panorama camera in the set of quick-accessvirtual cameras by default. In some embodiments, a user is enabled toselect one or more additional user-selected virtual cameras as quickaccess cameras from a set of candidate virtual cameras that are notincluded in the standard or default quick-access virtual cameras. Insome embodiments, one or more user-selected virtual cameras are added tothe set of quick-access virtual cameras in addition to the standard ordefault cameras in the set of quick-access virtual cameras (e.g., asquare camera and a black and white camera are added to the set ofquick-access virtual cameras). In some embodiments, one or more ofuser-selected virtual cameras replace one or more of the standard ordefault cameras in the set of quick-access virtual cameras (e.g., a userselects a square camera to replace the panorama camera in the set ofquick-access virtual cameras). In some embodiments, the non-selectedcandidate virtual cameras are still accessible to the user, but amulti-step set of different inputs is used to access the non-selectedcandidate virtual cameras (e.g., navigating through a series of menus toidentify and select a respective non-selected candidate virtual camera).In some embodiments, the set of quick-access virtual cameras has amaximum size (e.g., 3, 4, 5 or 6 virtual cameras), and the set ofcandidate virtual cameras includes more candidate virtual cameras (e.g.,10, 15 or 20 virtual cameras) than the maximum size of the set ofquick-access virtual cameras and thus there are some candidate virtualcameras that are not included in the set of quick-access virtualcameras. Thus, in some embodiments, the user is able to swipe to selectbetween one or more standard or default virtual cameras as well as oneor more user-selected virtual cameras rather than being forced tonavigate through a complicated set of menus to identify and selectvirtual cameras that are not standard or default virtual cameras.

In some embodiments, the touch-sensitive surface is part of atouchscreen display, and the second gesture includes movement of acontact across a camera preview displayed on the touchscreen display(670). For example, the gesture with contact 538 moves across touchscreen 112 over camera preview 508-2 (FIG. 5H).

In some embodiments, the touch-sensitive surface is part of atouchscreen display, and the second gesture includes movement of acontact across a portion of the touchscreen display that does notinclude any displayed affordances for controlling operation of thecamera (672). For example, the gesture with contact 538 moves acrosstouch screen 112 over camera preview 508-2 (FIG. 5H), and does not moveover any displayed affordance for controlling operation of the camera(e.g., camera roll icon 504; shutter button 506-2; control 534).

In some embodiments, the third camera interface provides (674) a visualindication of the third output dimensions (e.g., a panorama progressindicator for aligning sequential images in a panorama and that showsprogress toward capturing images that can be used to generate apanoramic image). For example, FIG. 51 shows windowboxing on camerapreview 508-3. FIG. 51 shows panorama progress indicator 550 displayedwith camera interface 502-4.

In some embodiments, the third output dimensions have (676) a differentaspect ratio than the first output dimensions and the second outputdimension. For example, camera interface 502-3 is associated with a 1:1aspect ratio, and camera interfaces 502-1, 502-2, and 502-4 areassociated with different aspect ratios.

In some embodiments, the third camera interface includes (678) one ormore controls that are not included in the first camera interface andthe second camera user interface (e.g., a panorama progress indicatorfor aligning sequential images in a panorama). For example, camerainterface 502-3 includes black-and-white control 544 that is notincluded in camera interfaces 502-1, 502-2, or 502-4. Camera interface502-4 includes panorama progress indicator 550 that is not included incamera interfaces 502-1, 502-2, or 502-3.

In some embodiments, the first virtual camera, the second virtual cameraand the third virtual camera use (680) a same physical camera sensorwith respective sensor dimensions to produce media, the media producedby one of the virtual cameras has dimensions that are smaller than therespective sensor dimensions of the physical camera sensor (e.g., squarecamera or video camera), and the media produced by a different one ofthe virtual cameras has dimensions that are larger than the respectivesensor dimensions of the physical camera sensor (e.g., panorama camerathat stitches together multiple images captured by the physical camerasensor to generate a panorama image). Camera interfaces 502 use the samephysical camera sensors on device 100. Camera interface 502-2 isassociated with output dimensions that are smaller than the sensordimensions. Camera interface 502-4 is associated with output dimensionsthat are larger than the sensor dimensions.

In some embodiments, the media produced by a different one of thevirtual cameras has (682) dimensions that are the same as (orsubstantially the same as) the sensor dimensions of the physical camerasensor (e.g., standard still camera). Camera interface 502-1 isassociated with output dimensions that are the same as the sensordimensions.

In some embodiments, the first camera interface, the second camerainterface and the third camera interface have (684) a set of one or morecommon controls, including a respective common control; and therespective common control is displayed in a same location on the displayin the first camera interface, the second camera interface and the thirdcamera interface. In some embodiments, the respective common control(e.g., the shutter button) has a same size and/or shape in each of thecamera interfaces. In some embodiments, the respective common controlhas a different color or appearance in two or more different camerainterfaces (e.g., the shutter button is gray or silver in a still camerauser interface and red in a video camera user interface). Camerainterfaces 502-1 thru 502-4 have camera roll icon 504 and shutter button506 in common. Camera icon 504 and shutter button 506 are respectivelydisplayed at the same respective locations across camera interfaces502-1 thru 502-4.

In some embodiments, the first camera interface, the second camerainterface, and the third camera interface include (686) a video camerainterface and two different still camera interfaces (e.g., one of thesethree camera interfaces is a video camera interface and the two othercamera interfaces are different still camera interfaces such as anoblong rectangular still camera and a panorama camera). For example,camera interface 502-1 and camera interface 502-3 (or 502-4) are stillcamera interfaces, and camera interface 502-2 is a video camerainterface.

In some embodiments, the first camera interface, the second camerainterface, and the third camera interface are selected (688) from theset consisting of: a rectangular still camera interface (e.g., an oblongrectangular still camera interface that is not square), a video camerainterface, a panorama still camera interface, a black and white stillcamera interface, and a square still camera interface. For example,camera interfaces 502-1, 502-2, 502-3, and 502-4 are a standard camerainterface (i.e., an oblong rectangular still camera interface), a videocamera interface, a square still camera interface, and a panorama stillcamera interface, respectively.
